Recover windows 2008 using software mirror

Hi,

If software mirroring is being used on a windows 2008  std server and the primary hard disk fails, what is the procedure to recover the windows installation?

Will plugging in a new hard disk recreate the original partitions?

Can someone point me to a guide on how to recover after such an event?

My server has not crashed, I am just exploring the possibility of using windows 2008 software mirror as a first level backup.

Thanks in advance

Amal
